Abstract
The utility model relates to an efficient clamp hydrocylinder, pertaining to the clamp tools in mechanical workout field. A current clamp, with a screw press plate structure which has to clip manually, is slow in operation, high in work intensity and low in automation, thus impairing process precision and quality. The utility model introduces a hydrocylinder and a spring structure, i.e. a spring is provided between the hydrocylinder piston and the top of the hydrocylinder; the piston rod threads through the spring and the plug screw of the hydrocylinder, and extends out of the hydrocylinder; a processing piece is installed on a screw which is in connection with the piston rod.Under the effect of oil pressure and spring force, the processing piece is clamped on the screw or loosened, reaching the purpose of assembly and dismantlement. With compact structure, easy operation and good manufacturability, the utility model is convenient to be standardized.
Description
Technical field
The utility model relates to the anchor clamps field in the machining.
Background technology
Anchor clamps adopt the artificial spiral press plate mechanisms that tighten more when the machine tooling workpiece at present, this spiral press plate mechanism automaticity is low, service speed is slow, labour intensity is big, and can't detect clamping force, when carrying was big, it was very inconvenient to operate, influence machining accuracy, and then influenced crudy.
Summary of the invention
The purpose of this utility model can guarantee crudy for providing a kind of easy to operate, the efficient clamping cylinder that automaticity is higher.
The technical scheme that realizes the foregoing invention purpose is: a kind of efficient clamping cylinder, end at oil cylinder has oil-in, the other end is the plug screw with the oil cylinder sealing, piston is housed in the middle of oil cylinder, between piston and plug screw, spring is housed, axially have screw passing the piston rod end that spring and plug screw stretch to outside the oil cylinder, the screw rod that workpiece is installed is housed in screw, packing ring and nut are housed in the screw rod end.
Spring in the oil cylinder adopts many group butterfly springs, and adjacent two disk springs are installed with involutory form.
A plurality of different directions have oil-in in the end of oil cylinder.
On the screw rod that workpiece is installed, a plurality of workpieces are housed.
The utility model utilizes butterfly spring to become the stiffness characteristics design.But when oil cylinder is oil-filled, piston overcomes spring force and moves to the oil cylinder other end, the spring compression, piston rod is protruding thereupon, workpiece is installed and is used nut screwing clamping, oil cylinder oil extraction then being connected on the screw rod of pistons end, the suffered pressure of spring disappears and resiles, the promotion piston reverses direction moves, and workpiece is tightened, and can process workpiece.After the completion of processing, oil-filled once more to oil cylinder, overcoming spring force towards oily back piston moves to the oil cylinder other end again, the workpiece of original clamping is unclamped, in the gap that forms between two workpieces about 0.3mm, at this moment very easily to turn on nut and unload workpiece, this moment, spring was compressed again by moving of piston, then reinstall new workpiece, saved the spring of energy and prepared once more workpiece to be clamped.
The utility model can in second clamp workpiece or unclamps at 2-3, this plays an important role to operating efficiency and assurance machining high-precision, the high-quality that improves lathe, the present invention also has compact conformation, simple to operate, work period is short, good manufacturability, safe and reliable, be convenient to standardized beneficial effect.
